cover arm64: defconfig: enable several options useful for ARM64 server platforms
ACPI-based ARM64 server platforms based, like the Qualcomm Datacenter Technologies QDF2400, need several features and drivers enabled for full functionality. This patchset enables many of those features.
The first patch, "resynchronize the defconfig" refreshes the ARM64 defconfig so that it's aligned with savedefconfig. This needs to be done periodically, so that new patches avoid merge conflicts.
If the first patch does not apply cleanly, I ask the maintainer to refresh it himself manually, following the instructions in the commit message. The remaining 7 patches should apply cleanly on top of that.

PATCH 1/8 arm64: defconfig: resynchronize the defconfig
Defconfig files become unsynchronized over time as Kconfig entries are added, removed, or changed. Making specific changes to the defconfig becomes difficult as unrelated differences can interfere. This problem is easily remedied:
make defconfig
make savedefconfig
cp defconfig arch/arm64/configs/defconfig
git add arch/arm64/configs/defconfig
git commit -s

I see there are patches queued in linux-next enabling some arm64 TPM CRB support, which I believe are related.
As I have commented elsewhere [1], I think those have been taken prematurely, and I'm not sure it's a good idea to enable this just yet, due to that. There are spec issues to be addressed in the draft that is still open.

So my research suggests that efivarfs is a replacement for CONFIG_EFI_VARS. We may still have some older programs that use the sysfs entries, but I'm not sure.
Regardless, I will drop EFI_VARS from v2 of the patset, and just set EFI_CAPSULE_LOADER.
